About Us

Care Tailored to Your Needs.
Upper Echelon Medical’s team of osteopathic doctors treats patients as a whole rather than focusing on a specific disease and believes in promoting the benefits of a healthy lifestyle before considering medications. The team also uses drug-free osteopathic manipulative techniques to help treat upper respiratory infections, headaches, back pain, muscle pain, and more.
For those patients who need medications to treat or help manage their condition, Upper Echelon Medical offers prescription dispensation, providing medicines at wholesale prices that save patients hundreds of dollars. This service is part of the practice’s direct primary care model, where patients pay a monthly fee rather than going through insurance companies.
